Delay-Scheduled State-Feedback Design for Time-Delay Systems with Time-Varying Delays

C. Briat, O. Sename, J.F. Lafay
2008 IFAC Proceedings Volumes  
This paper is concerned in the synthesis of delay-scheduled state-feedback stabilizing linear systems with time-varying delay when the delay can be approximatively known in realtime.  ...  First we introduce a new model transformation turning the time-delay system into an uncertain LPV system.  ...  It allows to consider a wider class of delay values and similarly turns a time-delay system into an uncertain LPV system where the delay acts now as a time-varying parameter.  ...
